I'm going to "show you what's behind the curtain", so to speak.
No, I'm not an "insider". In fact none of those people (JANG, Brickshow, just2good) would fit that description. We all have sources, some of them the same, that we get information and rumors from. Actually, a lot of this information comes from people (who work for or with LEGO) or retail chain websites (suppliers, partners, retailers) who let information slip, either by accident or very much on purpose.
Some of them take this information and use it for self-promotion, and often monetary gain. Brickshow and j2g would fit that bill. Note that there is nothing wrong with that - entire industries are devoted to deriving profit from information in the world. Sometimes some of these guys take it a bit far though.
JANG is his own thing - he's not part of the rumor machine. The guy just loves LEGO, and shares that with the world. Of course he makes a profit from his Youtube channel, but he buys so much LEGO, and sells so little of it, that I think most (if not all) of his profit is reinvested back into LEGO. I have a lot of respect for JANG, which I think shows in how often I reference his reviews.
The last true "insider" was GRogall. He is (was) either a LEGO employee or someone very close to one. For years he would provide the community with all sorts of advance information (with almost 100% accuracy) and with little to no self-promotion. He just liked to share what he knew. A little over a year ago GRogall fell off the face of the planet. Either he got caught, or he left the hobby, or something else happened. I have hoped it was for a positive reason.
So back to me. I like to think of myself as a mix of GRogall and JANG. I'm not in it for the profit (in fact this hobby is very expensive as you all know), but I love to share the information that I discover with my community, as to enrich it and promote discussion. I also realize that I've become one of the posters that can influence purchases, so I try to guide other GAF'ers towards what I consider to be the "better/best" sets out there currently. I've been approached by various sites for mentions and credit on rumors, and I turn them down if they ask, because that stuff doesn't matter to me. What matters to me is
bringing peace and order to the galaxy helping to keep LEGO-GAF as the Best-GAF.
